這篇文章主要介紹了Angular5中提取公共組件之radio list的實(shí)例代碼,非常不錯(cuò),具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

本文給大家說一下Radio List的公共組件提取。

Radio List組件提取起來很方便,不想Checkbox那么復(fù)雜。

radio-list.component.ts

import { Component, OnInit, Input, Output, EventEmitter } from '@angular/core';
import { RadioItem } from '../../model/radio';
import { NgModel } from '@angular/forms';
@Component({
  selector: 'app-radio-list',
  templateUrl: './radio-list.component.html',
  styleUrls: ['./radio-list.component.css']
})
export class RadioListComponent implements OnInit {
  @Input() list: RadioItem[];
  @Input() name: string;
  @Input() colNum: number = 6;
  @Input("selectModel") model: string;
  @Output("selectChange") onChange: EventEmitter<any> = new EventEmitter<any>();
  constructor() { }
  ngOnInit() {
  }
  changeSelected() {
    let data = { value: this.model, name: this.name };
    this.onChange.emit(data);
  }
}

radio-list.component.html

<div *ngIf="list" class="form-row">
  <div class="col-{{colNum}} mb-2" *ngFor="let item of list">
    <div class="form-check abc-radio abc-radio-primary">
      <input class="form-check-input" type="radio" [value]="item.id" [(ngModel)]="model" (change)="changeSelected()" name="{{name}}" id="{{name}}_{{item.id}}">
      <label class="form-check-label" for="{{name}}_{{item.id}}">
        {{item.name}}
      </label>
    </div>
  </div>
</div>

在相關(guān)引用的module中注冊(cè)

import { RadioListComponent } from '../components/radio-list/radio-list.component';
export const routes = [
  { path: '', component: xxxComponent, pathMatch: 'full' }
];
@NgModule({
  imports: [...],
  declarations: [...
    , RadioListComponent
    , ...],
  providers: []
})
export class xxxModule {
  static routes = routes;
}

對(duì)應(yīng)的html中引用如下:

 <app-radio-list [list]="sourceArr"
         [name]="'selectedSource'"
         [colNum]="12"
        [(selectModel)]="selectedSource"
        (selectChange)="selectChange($event)">
 </app-radio-list>

按照如上步驟,還缺少對(duì)應(yīng)的selectChange($event):

 selectChange(model: any) {
   this[model.name] = model.value;
 }

總結(jié)

以上所述是小編給大家介紹的Angular5中提取公共組件之radio list的實(shí)例代碼,希望對(duì)大家有所幫助,如果大家有任何疑問請(qǐng)給我留言,小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)腳本之家網(wǎng)站的支持!
